I tried this:
sudo nmcli radio all off
sudo rmmod 8723cs
sudo modprobe 8723cs
sudo nmcli radio all on

Did not work for me, still nothing found. We have a bunch of wifi signals here, so there should be plenty. If I tell it "nmcli r " it says everything is enabled, but no wifi networks listed. I start to think my phone has HW issues.
